Title:
非接触式通信媒体挿入口モジュール
Document Type and Number:
Japanese Patent JP4075754
Kind Code:
B2
Abstract:
An insertion-port loop antenna (1) has a wide communication region for a non-contact type IC card inserted into an insertion port of a card reader, etc. An insertion-port loop antenna (1) is mounted in the vicinity of an insertion port (23), through which a non-contact type communication medium is inserted. The insertion-port loop antenna (1) comprises two loops (20, 21). An upper loop (20) is arranged above a long side of the insertion port (23). A lower loop (21) is arranged below the long side of the insertion port (23). The two loops are opposite to each other in a direction of winding. Thereby, magnetic flux is generated between the upper loop and the lower loop. The magnetic flux is generated in front of the insertion port (23). Therefore, it is possible to begin communication before the non-contact type IC card (19) is inserted into the insertion port (23).
